A130 mm diameter cylinder fitted with a frictionless piston contains 0,03 kg of water at a pressure of 0.6 mpa and a temperature of 190°c. as the piston outwards through a distance constant, where p is in mpa and v is in m' and n is the polytropic exponent. the final pressure of the steam is 0.1 mpa. state all assumptions. find of 200 m m the water undergoes a polytropic process: pv"- (i) the value of the polytropic exponent, n (ii) the change in internal energy of water in k (ii) the change in enthalpy of water in kj (iv) the magnitude and sign of work transfer in the process in kj. (v) the magnitude and sign of heat transfer in the process in kj. (vi) show the process approximately in a p-v and a t-v diagram (vii) if the surroundings are at 200 'c does this process violate the 2ad law?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
